To provide an electrode sheet winding device capable of accurately winding an electrode sheet.

An electrode sheet winding device 1 carries an electrode sheet 2 and a separator 3, and winds the electrode sheet 2 while sandwiching the separator 3. The electrode sheet winding device 1 includes: a control portion 18 for calculating tilting amount N of thickness in a width direction; and a pair of correction rollers 16 disposed on a carrying path of the electrode sheet 2, and correcting a position in the width direction of the electrode sheet 2 on the basis of a calculation result of the tilting amount N of the thickness in the width direction.
